The energy difference between two electronic states is 43.5 kcal/Mole. The frequency of light emitted when the electron drops from higher orbit to lower orbit, is:(1)9.14×10^14 cycle/sec(2)45.7×10^14 cycle/sec(3)91.4×10^14 cycle/sec(4)4.57×10^14 cycle/secExplain?????
From planck's energy eqn.E = hv = hc/kwhere k is the wavelength put the values,43.5 x 10^3 x 4.2 = 6.64 x 10^-34 x vv = 27515 x 10^34 cycle/sec.
